用matlab实现的bezier n阶三角曲面生成算法(Generation algorithm implemented by matlab bezier n-order triangular surfaces)

基于解相干的MUSIC源程序,几类空间平滑MUSIC源程序：1、后向空间平滑MUSIC源程序；2、前向空间平滑MUSIC源程序；3、双向空间平滑MUSIC源程序；(Based on decorrelation MUSIC source, several types of spatial smoothing MUSIC source: 1, backward spatial smoothing MUSIC source 2 forward spatial smoothing MUSIC source 3, two-way spatial smoothing MUSIC source )

高斯平滑滤波，属于低通滤波，有效去除图像噪声。(Gaussian smoothing filter, a low pass filter effectively removes image noise.)

对于一个含有明显噪声的心电信号进行卡尔曼滤波处理，最大程度地 “还原”信号，达到去除噪声的目的。卡尔曼滤波（看成维纳滤波的一种实现方法）的特点如下： a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。 b) 它是用状态方程和递推方法进行估计的，因而卡尔曼滤波对信号的平稳性和时不变性不做要求。 c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)

逆合成孔径雷达（ISAR）具有远距离、全天候、全天时工作等优点，目前通过ISAR成像来进行目标识别已得到广泛的应用。ISAR的观测对象是非合作目标，因此ISAR成像具有深远的国防应用背景，受到各国的重视，是竞争激烈、发展迅速的技术领域。(Inverse Synthetic Aperture Radar (ISAR) has a long-range, all-weather, all-time work, etc, currently conducted by ISAR imaging for target identification has been widely used. ISAR target non-cooperative target observation, it has far-reaching defense ISAR imaging application background, attention all, is highly competitive, rapidly developing technology.)
